The global industrial development, the increasing demand for energy, the limited availability of resources for the future generations of fossil fuels, and the prevention of environmental damage caused by their burning have led to public concern. Increasing energy consumption by buildings has led the wider global attention to its social, environmental, and economic implications. In the present study, in order to reduce the power consumption of the summer, a solar vacuum tube-collecting system, with its high efficiency, with a hot water tank and an absorption refrigeration system in a 5-story residential building in In Tehran Capital of Iran, has been investigated. In addition, the results also indicate that the main source of exergy destruction is solar collectors. In the solar collector, we have 93.22% of the exergy destruction, which accounts for 92.8% of the total exergy cascade. In addition, 18.45% of the exergy destruction occurred in the generator, which was equivalent to 1.598% of the total exergy casualties. Also, the coefficient of performance and exergy efficiency of the whole system were 0.746 and 23.5%, respectively, which showed a significant increase in total exergy efficiency compared to the conventional refrigeration system.
